The BlackBerry Z10 offers a 4.2" display with an aspect ratio of 15:9 and WXGA resolution (1280 x 768 pixels). Those figures add up to a nicely sounding 355 ppi pixel density, which means the screen is tack sharp and you’d be hard pressed to discern individual pixels. It's not as good as the Oppo Find 5 and its 1080p 5-incher, but you'd have to be looking from way closer than feels comfortable to tell the difference.
The image quality is quite good, too. Native contrast is excellent, viewing angles are very wide and colors are very lively. The Z10 is not the best in any of these aspects but it's close enough to the top to make everything on the screen look punchy.

The maximum brightness setting is just above average, but there's no way for you to disable the automatic brightness control. The reflectivity of the screen is reasonably low, so we didn't have any issues with sunlight legibility.
